.disable | .enable materialized-view

A materialized view can be disabled in any of the following ways:

  • Automatic disable by the system: Materialized view is automatically disabled if materialization fails with a permanent error. This process can occur in the following instances:
    • Schema changes that are inconsistent with the view definition.
    • Changes to source table that result in the materialized view query being semantically invalid.
  • Explicitly disable the materialized view: If the materialized view is negatively impacting the cluster's health (for example, consuming too much CPU), disable the view using the command below.


  • When a materialized view is disabled, materializing will be paused and won't consume resources from the cluster. Querying the materialized view is possible even when disabled, but performance can be poor. Performance on a disabled materialized view depends on the number of records that were ingested to the source table since it was disabled.
  • You can enable a materialized view that has previously been disabled. When re-enabled, the materialized view will continue materializing from the point it left off, and no records will be skipped. If the view was disabled for a long time, it may take a long time to catch up.

Disabling a view is only recommended if you suspect that the view is impacting your cluster's health.

Property Type Description
MaterializedViewName String Name of the materialized view.


.enable materialized-view ViewName

.disable materialized-view ViewName

If a row level security policy is defined on the source table of a view that has been disabled, and the materialized view doesn't have a row level security policy defined, enabling it will fail due to security reasons. To mitigate this error, you can:

  • Define the row level security policy over the materialized view.
  • Choose to ignore the error by adding allowMaterializedViewsWithoutRowLevelSecurity property to the enable policy command. For example:
    .enable materialized-view MV with (allowMaterializedViewsWithoutRowLevelSecurity=true)
